This U.S. patent application claims priority from U.S. provisional patent application Ser. No. 60/806,289, filed 30 Jun. 2006.
The method relates to using a cord holder such as a cord holder that may, for example, be used to roll up and roll out a flexible cord.
A variety of cords and wires are commonly used to connect electronic equipment. For example, cords are used to connect music players/mobile phone with headsets or headphones. Cords are also used to connect various components of stereo and computer equipment. These cords sometimes get in the way and there is a need to adjust the length of the cords to the specific application. There are roll-up devices provided by the music player manufacturers so the roll-up devices are made to be permanently used together the manufacturer's own music player/mobile phone. These devices are often permanently connected to the headset cord so that the consumer cannot select his/her own preferred headset when such the roll-up devices. In other words, the user cannot use an existing headset with the currently available cord roll-up devices. There is a need for a method of using a cord holder that permits the user to select his/her preferred headset, or any other electronic equipment, while having access to the roll-up function of a cord holder.
The method of the present invention provides a solution to the above-outlined problems. More particularly, the method is for using a cord holder. A cord holder has a bottom cover and a removable top cover with a spring bracket disposed therebetween. The removable top cover may be removed from the bottom cover without removing a spring from a spring bracket so that the spring remains in the spring bracket and the bottom cover while the top cover is removed. A cord is placed around a first spacer and a second spacer of the spring bracket. A knob is pressed to permit a spring, disposed inside the spring bracket, to roll up the cord. It is possible to tension the spring even when the top cover and the cord are removed from the spring bracket since the spring is disposed in the interior space under the spring bracket.
With reference to
The bottom cover 12 has a central upwardly protruding axle 18. A spring holder 20 is disposed next to the axle 18. A bottom surface 22 of the bottom cover 12 has a spring holding protrusion 24 for holding one end of a spring and a bracket-engaging unit 26 for permitting a rewindable knob 76 to be inserted into and serve as an axle for the knob 76. Both the protrusion 24 and the engaging unit 26 are disposed close to a peripheral end wall 28. A cavity 30 is defined in the end wall for receiving a cord 32 and a cavity 34 is defined at an opposite end diametrically opposite the cavity 30. The cord may be any suitable bendable elongate member such as cables, cords and wires. The end wall 28 also has a knob receiving opening 36 defined therein.
The spring bracket 16 has a bottom cog 38 and a disc 40 held separate by a first centrally mounted spacer 42 so that a groove 44 is defined therein. The cog 38 has teeth 39 so that the cog may be easily moved in one direction but there is a resistance to move the cog in the opposite direction when the teeth are engaged.
A second groove 46 is defined above the disc 40. The disc 40 has a second spacer 48 centrally mounted thereon. The second spacer 48 has a first slit 50 and a second slit 52 defined in the sidewall thereof. The slit 52 is aligned with a slit 53 of the disc 40 so that the cord 32 may extend between the top groove 46 and the bottom groove 44 via the slit 53. A half circular member 55 is disposed inside the spacer 48 so that a space 54 is defined therebetween to receive the cord 32. In this way, about half the length of the cord may be rolled up around the second spacer 48 and the other half the length may be rolled up around the first spacer 42.
An e-ring 62 may be used to lock the spring bracket 16 to the bottom cover 12 by snapping the e-ring 62 into a cavity 64 defined at a top of the axle 18 when the axle is inserted trough a central opening 66 of the spring bracket 16. The e-ring 62 is important because the top cover 14 and the cord 32 can be removed without the locking mechanism and spring popping out.
The top cover 14 has a clip 56 is mounted to a top surface of the top cover 14. The clip 56 may be used to hang the cord holder 10 to items such as an outside, loudspeaker, pocket or suit jacket or any other suitable item. A sidewall 58 has a cavity 60 defined therein that cooperates with the cavity 34 when the top cover 14 is placed over the bottom cover 12.
As indicated above, the rewindable knob 76 may be used to roll up and pull out the cord 32. It is not necessary to use the knob when pulling out the knob since it is spring biased by the spring. The knob has an engagement member 78 that engages the teeth 39 when the knob is placed in the opening 36. The knob 76 may be pushed in and pulled out to engage and disengage the teeth 39. Because the knob is spring biased it is not necessary for the user to pull out the knob but only to press the knob when the cord is to be pulled out. As a result the cord 32 can be automatically rolled in as a result of a tension of a spring, as explained below. The cord 32 may be pulled out by simply pulling on the cord 32.
As best shown in
One important feature of the cord holder 10 of the present invention is that the user can easily and conveniently adjust the length of any cord 32. The use for headsets is merely an illustrative example. The cord holder may be used to hold any cord or wire such as loudspeaker cords or any other electrical wire or cord. Another important feature is that the spring 68 is positioned away from the cord 32 so that the spring does not interfere with any removal or inserting of the cord into the spring bracket 16. It is even possible to tension the spring 68 while the top cover 14 and the cord 32 are removed from the spring bracket 16. The user simply rotates the spring bracket 16 relative to the bottom cover 12 to tension the spring 68 disposed inside the interior space 70.
While the present invention has been described in accordance with preferred compositions and embodiments, it is to be understood that certain substitutions and alterations may be made thereto without departing from the spirit and scope of the following claims.
